Normas Internacionales de Auditoría: identificación del cumplimiento de las disposiciones legales y reglamentarias conforme la NIA 250, en la Empresa Importadora Reyes del Departamento de Managua
El presente seminario comprende la responsabilidad del auditor al practicar una auditoría financiera de considerar cada una de las normas legales que rigen el marco normativo de una entidad, ya que algunas poseen regulaciones specíficas como lo es el caso de las entidades financieras y farmacias, pero otras en su mayoría obedecen a diversas leyes. Esta investigación es de suma importancia porque establece los efectos que se derivan cuando una organización en la preparación de sus estados financieros ha quebrantado lo dispuesto por sus regulaciones aplicables.
En el proceso de investigación se consultó y recopilo información de diferentes fuentes entre las que destacan: libros de auditoria y contabilidad, sitios web, entrevistas, NIIF para PYMES, NIAS y las diferentes leyes que rigen las operaciones del sector importación de las entidades en Nicaragua, todo ello para determinar el cumplimiento de las mismas mediante un caso práctico.
De los resultados obtenidos se puede expresar que la empresa importadora Reyes ha presentado su información financiera cumpliendo con la mayoría de las regulaciones que la rigen a excepción con lo dispuesto por las regulaciones aduaneras, porque se omitió información de la mercadería importada al momento de realizar la declaración en aduana, y con lo estipulado en la ley de concertación tributaria, referente a la realización de pagos tardíos de las obligaciones tributarias
Report AtlantOS fitness for offshore aquaculture siting
European policy intends to expand the space available to aquaculture by cultivating sites that are offshore. This presents challenges in terms of building structures, e.g., fish cages that withstand the effects of offshore weather conditions along the Atlantic coast. In order to establish possible future sites for offshore aquaculture production AtlantOS T8.5 gathered relevant wave, current velocity and water column structure measurements from the coasts of Ireland, Norway and Spain and used these data to validate site assessment models of the potential new offshore aquaculture sites. This deliverable report assesses the fitness for purpose of the generic aquaculture decision support tool developed
New records of Chondrichthycians species caught in the Cantabrian Sea (southern Bay of Biscay)
Seventeen chondrichthyan species were caught in the Cantabrian Sea (southern Bay of Biscay) during a multidisciplinary
survey carried out in the Avile´s canyon system in May 2011. This survey provided the first records of three species (Galeus
murinus, Neoraja iberica, and Neoraja caerulea) in these waters, and a further record of Rajella kukujevi. To confirm the
identity of these species, the cytochrome c oxidase subunit I (COI) of the specimens was sequenced. Genetic analyses revealed
that the DNA sequences of the two Neoraja species were identical in all the specimens analysed. Morphometric analyses, based
on 40 characters, showed 3.66% dissimilarity between the two species. The morphometric character that contributed most to
this discrepancy was disc width.Versión del editor1,023
Endovascular treatment of a patient with an aneurysm of the proper hepatic artery and a duodenal fistula
Aneurysms of the proper hepatic artery comprise a rare but potentially dangerous entity for which treatment is performed both surgically and endovascularly. Covered stents are generally used for endovascular treatment of such aneurysms. When the aneurysm is contaminated due to an enteric fistula, however, use of a covered stent is considered inappropriate. This case report describes the endovascular repair of a proper hepatic artery aneurysm using overlapping bare metal stents after the patient was surgically treated for duodenal hemorrhage
Technical note: Productive variables of Pelibuey lambs and ewes induced to estrus with exogenous hormones and with different types of suckling
With the objective of analyzing the productive and reproductive response of lambs and ewes subjected to induced or synchronized estrus and to three different types of suckling, 60 Pelibuey ewes and their lambs were randomly assigned, at seven days postpartum, to one of three groups (n = 20); continuous suckling (AC), restricted suckling (AR) and early weaning (DP). The animals were weighed weekly from birth until the eighth week. At 30 d postpartum, the hormonal treatment applied was intravaginal progestagen (P4) plus 0.05 mg of PGF2á and 300 UI of eCG two days before the removal of P4. The percentage of estrus was higher (95%) in DP and AR groups compared with AC (60%; P < 0.05), as was fertility (DP, 80%; AR 75%) versus 40% in AC (P < 0.05), and prolificacy (lambs/ewe, 1.87 and 1.5; P < 0.05). Weight of lambs at 8 wk of age was higher for AC (16.8) and AR (16.5) than for DP (11.9 kg; P < 0.05). In conclusion, the restriction of suckling and early weaning, improved the reproductive efficiency in Pelibuey ewes. However, DP reduced weight gain of the lambs and increased their mortality rate relative to AC and AR
Physical Exercise following bariatric surgery in women with Morbid obesity Study protocol clinical trial (SPIRIT compliant)
Background: Severe and morbid obesity are increasing globally, particularly in women. As BMI increases, the likelihood of
anovulation is higher. The primary aim of the EMOVAR clinical trial is to examine, over the short (16 weeks) and medium (12 months)
term, the effects of a supervised physical exercise program (focused primarily on aerobic and resistance training) on ovarian function
in women with severe/morbid obesity who have undergone bariatric surgery. Secondary objectives are to examine the effects of the
intervention on chronic inflammation, insulin resistance, arterial stiffness, physical fitness, and health-related quality of life.
Methods: This is a randomized controlled trial in which ∼40 female bariatric surgery patients, aged between 18 and 45 years old, will
be included. Participants assigned to the experimental group will perform a total of 48 sessions of supervised concurrent (strength and
aerobic) training (3sessions/week, 60min/session) spread over 16 weeks. Patients assigned to the control group will receive lifestyle
recommendations. Outcomes will be assessed at baseline, week 16 (i.e., after the exercise intervention) and 12 months after surgery.
The primary outcome is ovarian function using the Sex-Hormone Binding Globuline, measured in serum. Secondary outcomes are
serum levels of anti-mullerian hormone, TSH, T4, FSH, LH, estradiol, prolactine, and free androgen index, as well as oocyte count, the
diameters of both ovaries, endometrial thickness, and uterine arterial pulsatility index (obtained from a transvaginal ultrasound), the
duration of menstrual bleeding and menstrual cycle duration (obtained by personal interview) and hirsutism (Ferriman Gallwey Scale).
Other secondary outcomes include serummarkers of chronic inflammation and insulin resistance (i.e., C-reactive protein, interleukin 6,
tumor necrosis factor-alpha, leptin, glomerular sedimentation rate, glucose, insulin and theHOMA-IR), arterial stiffness, systolic, diastolic
and mean blood pressure, body composition, and total weight loss. Physical fitness (including cardiorespiratory fitness, muscular
strength, and flexibility), health-related quality of life (SF-36 v2) and sexual function (Female Sexual Function Index) will also be measured.
Discussion: This study will provide, for the first time, relevant information on the effects of exercise training on ovarian function and
underlying mechanisms in severe/morbid obese women following bariatric surgery.This work was supported by Ministerio de Economía y Competitividad (MINECO), Plan Nacional de I+D+i call RETOS 2018 (grant n° RTI2018-093302-A-I00). EM-R

International Exercise Recommendations in Older Adults (ICFSR): Expert Consensus Guidelines
The human ageing process is universal, ubiquitous and inevitable. Every physiological function is being continuously diminished. There is a range between two distinct phenotypes of ageing, shaped by patterns of living - experiences and behaviours, and in particular by the presence or absence of physical activity (PA) and structured exercise (i.e., a sedentary lifestyle). Ageing and a sedentary lifestyle are associated with declines in muscle function and cardiorespiratory fitness, resulting in an impaired capacity to perform daily activities and maintain independent functioning. However, in the presence of adequate exercise/PA these changes in muscular and aerobic capacity with age are substantially attenuated. Additionally, both structured exercise and overall PA play important roles as preventive strategies for many chronic diseases, including cardiovascular disease, stroke, diabetes, osteoporosis, and obesity; improvement of mobility, mental health, and quality of life; and reduction in mortality, among other benefits. Notably, exercise intervention programmes improve the hallmarks of frailty (low body mass, strength, mobility, PA level, energy) and cognition, thus optimising functional capacity during ageing. In these pathological conditions exercise is used as a therapeutic agent and follows the precepts of identifying the cause of a disease and then using an agent in an evidence-based dose to eliminate or moderate the disease. Prescription of PA/structured exercise should therefore be based on the intended outcome (e.g., primary prevention, improvement in fitness or functional status or disease treatment), and individualised, adjusted and controlled like any other medical treatment. In addition, in line with other therapeutic agents, exercise shows a dose-response effect and can be individualised using different modalities, volumes and/or intensities as appropriate to the health state or medical condition. Importantly, exercise therapy is often directed at several physiological systems simultaneously, rather than targeted to a single outcome as is generally the case with pharmacological approaches to disease management. There are diseases for which exercise is an alternative to pharmacological treatment (such as depression), thus contributing to the goal of deprescribing of potentially inappropriate medications (PIMS). There are other conditions where no effective drug therapy is currently available (such as sarcopenia or dementia), where it may serve a primary role in prevention and treatment. Therefore, this consensus statement provides an evidence-based rationale for using exercise and PA for health promotion and disease prevention and treatment in older adults. Exercise prescription is discussed in terms of the specific modalities and doses that have been studied in randomised controlled trials for their effectiveness in attenuating physiological changes of ageing, disease prevention, and/or improvement of older adults with chronic disease and disability. Recommendations are proposed to bridge gaps in the current literature and to optimise the use of exercise/PA both as a preventative medicine and as a therapeutic agent
Clonación de genotipos adultos y juveniles de Quercus suber y Q. ilex tolerantes a Phytophthora cinnamomi
El síndrome de “la seca” está generando desde hace décadas la pérdida de masas de Quercus
mediterráneos provocando grandes pérdidas económicas y ecológicas. Por ello, en 2019 el
subgrupo de “Mejora Genética y Fisiología” del Grupo de Trabajo sobre Seca del Ministerio para la
Transición Ecológica y el Reto Demográfico impulsó el Programa Nacional para la Conservación y
Mejora de Recursos Genéticos de Encina y Alcornoque. Este programa contempla la clonación y la
conservación de material tolerante a Phytophthora cinnamomi y/o sequía, seleccionado en
anteriores proyectos de investigación. Aplicando técnicas de cultivo in vitro, embriogénesis somática
y proliferación de yemas axilares, se pretende clonar una selección de individuos dentro de las
progenies más tolerantes, y los mejores genotipos adultos evaluados a través de esas progenies.
Las hojas son el explanto elegido para inducir embriones somáticos en material juvenil y adulto de
alcornoque; en material de encina adulto el explanto inicial es el tegumento del embrión inmaduro.
Las líneas embriogénicas generadas han sido conservadas a largo plazo mediante su
crioconservación (almacenamiento en nitrógeno líquido). La proliferación de yemas axilares se
emplea para clonar genotipos juveniles de ambas especies. La clonación del material permitirá
disponer de copias suficientes que permitan la evaluación de su tolerancia en ensayos de campo

The measurement of bilingual abilities: central challenges
In this handbook chapter I analyse the concept of bilingual abilities. Bilinguals vary widely in what they can do with their languages or in the ways in which they use their languages on a daily basis. This means that there is a great deal of variability in what the term covers. While many researchers subscribe to the holistic view of bilingualism, in the academic literature bilinguals are still often described in negative terms as having a "deficit" in one or another subsystem of their languages. The key aim of this chapter is to identify what makes individuals with bilingual abilities unique speaker-hearers in their own right, avoiding the fractional view of bilingualism, and how these abilities can be measured
